845800e190 Don't use memcpy() in the early microcode loading code.
At some point memcpy() may be an ifunc, ifunc resolution cannot be done
until CPU identification has been performed, and CPU identification must
be done after loading any microcode updates.

398810619c Support reading from the arm64 ID registers from userspace.
Trap reads to the arm64 ID registers and write a safe value into them. This
will allow us to put more useful values in these later and have userland
check them to find what features the hardware supports.

These are currently safe defaults, but will later be populated with better
values from the hardware.

r330951 by smh fixed the mps driver to avoid deadlocks when panicing.
The same code is needed for mpr, so port it here, along with the fix
which allows the CCBs scheduled to complete avoiding at least a scary
message and likely other unintended consequences.

d4b95382ee Call xpt_sim_poll in shutdown_final handler.
When we're shutting down, we send a number of start/stop commands to
the known targets. We have to wait for them to complete. During a
panic, the interrupts are off, and using pause to wait for them to
fire and complete won't work: we have to poll after pause returns so
the completion routines of the CCBs run so we decrement work
outstanding counts.

0cc28e3cd5 Create xpt_sim_poll and refactor a bit using it.
xpt_sim_poll takes the sim to poll as an argument. It will do the
proper locking protocol, call the SIM polling routine, and then call
camisr_runqueue to process completions on any CCBs the SIM's poll
routine completed. It will be used during late shutdown when a SIM is
waiting for CCBs it sent during shutdown to finish and the scheduler
isn't running because we've panic'd.

This sequence was used twice in cam_xpt, so refactor those to use this
new function.

48f2b00648 evdev: Remove evdev.ko linkage dependency on kbd driver
Move evdev_ev_kbd_event() helper from evdev to kbd.c as otherwise evdev
unconditionally requires all keyboard and console stuff to be compiled
into the kernel. This dependency happens as evdev_ev_kbd_event() helper
references kbdsw global variable defined in kbd.c through use of
kbdd_ioctl() macro.

While here make all keyboard drivers respect evdev_rcpt_mask while setting
typematic rate and LEDs with evdev interface.

97edfc1b45 Implement kernel support for early loading of Intel microcode updates.
Updates in the format described in section 9.11 of the Intel SDM can
now be applied as one of the first steps in booting the kernel.  Updates
that are loaded this way are automatically re-applied upon exit from
ACPI sleep states, in contrast with the existing cpucontrol(8)-based
method.  For the time being only Intel updates are supported.

Microcode update files are passed to the kernel via loader(8).  The
file type must be "cpu_microcode" in order for the file to be recognized
as a candidate microcode update.  Updates for multiple CPU types may be
concatenated together into a single file, in which case the kernel
will select and apply a matching update.  Memory used to store the
update file will be freed back to the system once the update is applied,
so this approach will not consume more memory than required.

c1344d2bbe Prevent some parallel swap-ins, rate-limit swapper swap-ins.
If faultin() was called outside swapper (from PHOLD()), do not allow
swapper to initiate additional swap-ins.  Swapper' initiated swap-ins
are serialized because they are synchronous and executed in the
context of the thread0.  With the added limitation, we only allow
parallel swap-ins from PHOLD(), which is up to PHOLD() users to
manage, usually they do not need to.

Rate-limit swapper' swap-ins to one in the MAXSLP / 2 seconds
interval, counting faultin() swapins.

5ccac9f972 lagg: allow lacp to manage the link state
Lacp needs to manage the link state itself. Unlike other
lagg protocols, the ability of lacp to pass traffic
depends not only on the lagg members having link, but also
on the lacp protocol converging to a distributing state with the
link partner.

If we prematurely mark the link as up, then we will send a
gratuitous arp (via arp_handle_ifllchange()) before the lacp
interface is capable of passing traffic. When this happens,
the gratuitous arp is lost, and our link partner may cache
a stale mac address (eg, when the base mac address for the
lagg bundle changes, due to a BIOS change re-ordering NIC
unit numbers)
